I found this ant colony in a family trip to Grand Canyon, it reminds me of Monomorium minimum.
Sorry for the really bad quality, when I took the photos, I wasn't expecting to post it. I'll try to describe them as best as I can.
They were quite skittish and small, with slender bodies and black carapace.
This is their mound:
